Early Gait Function After Lung Transplantation in Patients With and Without Pretransplant Extracorporeal Membrane Oxygenation Support

Abstract

Objective: We aimed to investigate the recovery of gait function, muscle strength, and the achievement of an independent gait after lung transplantation (LT) in patients with and without pretransplant extracorporeal membrane oxygenation (ECMO) support.

Methods: We retrospectively reviewed the medical records of 33 inpatients who underwent bilateral LT and received physical therapy. We assessed the Functional Ambulatory Category (FAC) and Manual Muscle Test (MMT) scores at baseline, 1 month, and 3 months of rehabilitation and the time it took to achieve a FAC score of 3 within 3 months of LT surgery in ECMO and non-ECMO patients.

Results: The FAC and MMT scores were generally improved during the first 3 months after LT. The number of patients who achieved a FAC score of 3 at 3 months did not significantly differ between the ECMO and non-ECMO groups (P = .193). At 1 month, significantly fewer patients had reached a FAC of 3 in the ECMO group than in the non-ECMO group (P = .042). There were no significant differences in the FAC (P = .398) and MMT scores (P = .079) at 3 months between the 2 groups.

Conclusions: Both groups' gait function and muscle strength were continuously restored 3 months after LT. At 1 month, the gait function was assessed by the FAC score, and the rate to achieve a FAC of 3 was higher in the non-ECMO group than in the ECMO group, but at 3 months, the difference was not significant between the 2 groups.
